This series add support to build pci-j721e driver and pcie-cadence library as lodable modules. Changes from v1: * Reword subject line to use PCI in place of PCIe to maintain consistency with older commit messages. * Fix word wrapping in commit message to 75 columns and add newline between paragraphs. * Drop PATCH 3 (defconfig changes) from v1 and will repost it separately.
